It depends on where you at in general income, I guess? I prefer to stockpile. Last time I think they put out eight CEO items at once, which was a bit much without having a reserve of tickets. Also, just in case I don't have time to farm tickets when the next gains week comes around, it's good to have a buffer.

If you fell you need more multiplier, I'd go for it though. Someone said the max multiplier level was 50, and I'm pretty close to that, so I'm not in a hurry to get there and lose future multipliers. However, if you think raising your multiplier will really help get you to the max prize in the weekend tournament, that's probably more value for your tickets than waiting for the next gains week.
